Meat eaters in developed countries will have to eat a lot less meat, cutting consumption by 50%, to avoid the worst consequences of future climate change, new research warns.
The fertilisers used in farming are responsible for a significant share of the warming that causes climate change.
A study published in Environmental Research Letters  warns that drastic changes in food production and at the dinner table are needed by 2050 in order to prevent catastrophic global warming.
It’s arguably the most difficult challenge in dealing with climate change: how to reduce emissions from food production while still producing enough to feed a global population projected to reach 9 billion by the middle of this century.
